Speaking to The Sun, an Amazon spokesperson confirmed that the ambassadors have worked in fulfilment centres, but now perform their online shilling duties full time.

"FC ambassadors are employees who have experience working in our fulfilment centres," the spokesperson explained.

"The most important thing is that they’ve been here long enough to honestly share the facts based on personal experience.

"It’s important that we do a good job of educating people about the actual environment inside our fulfillment centres, and the FC ambassador program is a big part of that along with the fulfilment center tours we provide.

"Those tours enable thousands of customers every year to come and see for themselves what it’s like to work inside one of our fulfilment centres."

Amazon added that employees receive the same compensation and benefits as they did during their warehouse roles.

The Twitter propaganda push is clearly an effort to improve Amazon's poor reputation.

Amazon has regularly been the target of complaints from workers over so-called "abusive treatment" – including FACE, a group of former staffers dedicated to lobbying Amazon to clean up its act.

In 2011, a total of 19 Amazon workers spoke to Pennsylvania's Morning Call about having to working in extreme heat, and undergo strenuous workloads.

Then in 2013, the Daily Mail exposed Amazon for GPS tagging employees.

A Channel 4 documentary at the same time captured secret footage documenting worker abuses, and called warehouse work practices "horrendous and exhausting".

In November 2016, the BBC produced an undercover report that found some delivery drivers were having to break speed limits and go to the toilet in their vans to save time.

It also emerged that some drivers were being paid £2.59 an hour after deducations, less than half the UK's minimum wage.

The next month, workers at the Dumfermline, Scotland fulfilment centre were pictured camping outside the warehouse in the winter to avoid commuting costs.

Then in December 2017, a report by the Sunday Mirror suggested Amazon drivers will still making less than the minimum wage after paying for van hire and insurance.

In a statement about workplace conditions, an Amazon spokesperson told The Sun: "Amazon provides a safe and positive workplace for thousands of people across the UK with competitive pay and benefits from day one.

"We have a focus on ensuring we provide a great environment for all our employees and Amazon was recently named by LinkedIn as the 7th most sought after place to work in the UK and ranked first place in the US.

"Amazon also offers public tours of its fulfilment centres so customers can see first-hand what happens after they click “buy” on Amazon by visiting uk.amazonfctours.com.

"The scanning devices we use are common across the warehouse and logistics sector as well as in super markets, department stores and other businesses, and are designed to assist our people in preforming their roles. We do not use GPS to monitor people’s location in our fulfilment centers or for any other purpose.

"Our delivery providers are contractually obligated to ensure drivers they engage receive the National Living Wage and are expected to pay a minimum of £12 per hour, follow all applicable laws and driving regulations and drive safely. Allegations to the contrary do not represent the great work done by around 100 small businesses generating thousands of work opportunities for delivery drivers across the UK."
